In addition to executing normal business processing for managing payments received from customers by transfer or transfer, load leveling processing is executed in each of the power demand groups G1 to G3.

ここで、負荷平準化処理は、図２に示すように、先ず、ステップＳ１で、電力需要がピーク需要に近づいたか否かを判定し、ピーク需要に近づいたときにはステップＳ２に移行して、各電力需要グループＧ１〜Ｇ３の需要家Ｄ１１〜Ｄ１ｎ、Ｄ２１〜Ｄ２ｍ及びＤ３１〜Ｄ３５に対して負荷低減指示を送信してからステップＳ３に移行し、ピーク需要に近づいていないときには直接ステップＳ３に移行する。   Here, as shown in FIG. 2, in the load leveling process, first, in step S1, it is determined whether or not the power demand is close to the peak demand. After transmitting a load reduction instruction to the consumers D11 to D1n, D21 to D2m, and D31 to D35 of the power demand groups G1 to G3, the process proceeds to step S3. When the peak demand is not approached, the process directly proceeds to step S3. .

このステップＳ３では、各電力需要グループＧ１〜Ｇ３の需要家Ｄ１１〜Ｄ１ｎ、Ｄ２１〜Ｄ２ｍ及びＤ３１〜Ｄ３５から送信される電力使用量を読込んで、各電力需要グループＧ１〜Ｇ３毎の電力使用総量を算出し、次いでステップＳ４に移行して、算出した電力使用総量が各電力需要グループＧ１〜Ｇ３毎に予め設定されたピーク時閾値を超えているか否かを判定し、電力使用総量がピーク時閾値を超えているときにはステップＳ５に移行して、予め設定された電力の制限を行っても影響が少ない電力機器について電力の制限又は供給停止を行う電力低減指令を送信してからステップＳ６に移行し、電力使用総量がピーク時閾値を下回っているときには直接ステップＳ６に移行する。   In this step S3, the power usage amount transmitted from the consumers D11 to D1n, D21 to D2m and D31 to D35 of each power demand group G1 to G3 is read, and the total power usage amount for each power demand group G1 to G3 is obtained. Then, the process proceeds to step S4, where it is determined whether or not the calculated total power usage exceeds a peak threshold set in advance for each power demand group G1 to G3, and the total power usage is the peak threshold When the power limit is exceeded, the process proceeds to step S5, and a power reduction command for power limitation or supply stop is transmitted for a power device that has little influence even if a preset power limit is performed, and then the process proceeds to step S6. When the total power consumption is below the peak threshold, the process directly proceeds to step S6.

このステップＳ６では、オフピーク状態であるか否かを判定し、オフピーク状態であるときにはステップＳ７に移行して、冷凍・冷蔵倉庫に対してフル稼動指令を出力して、冷凍・冷蔵温度を通常状態より低く温度に冷却し、次いでステップＳ８に移行して、エネルギ貯蔵装置６や床暖房装置ＦＤ２１〜ＦＤ２ｍ、ハウス栽培装置Ｄ３４、養殖装置Ｄ３５等のオフピーク時電力需要機器を稼動状態としてしてから前記ステップＳ１に戻り、前記ステップＳ６の判定結果がオフピーク状態ではないときにはそのまま前記ステップＳ１に戻る。   In this step S6, it is determined whether or not it is in an off-peak state. If it is in an off-peak state, the process proceeds to step S7, a full operation command is output to the freezing / refrigerated warehouse, and the freezing / refrigeration temperature is set to the normal state. After cooling to a lower temperature and then proceeding to step S8, the off-peak power demand equipment such as the energy storage device 6, the floor heating devices FD21 to FD2m, the house cultivation device D34, the aquaculture device D35, etc. are put into operation, and then Returning to step S1, when the determination result of step S6 is not in the off-peak state, the process returns to step S1 as it is.

この図２の処理において、ステップＳ６〜Ｓ８の処理がオフピーク時管理手段に対応している。
また、システム管理装置ＳＤは、データベースに格納されている各電力需要グループの所定時刻毎の総電力使用量を算出して図３に示すタイムチャートを形成し、このタイムチャートから平準化目標総電力使用量を算出し、算出した平準化目標総電力使用量を下回る所定時刻毎の総電力使用量が存在するか否かを判定し、平準化目標総電力使用量を下回る総電力使用量が存在する場合には、平準化目標総電力使用量から総電力使用量を減算した電力量偏差ΔＷを算出し、この電力量偏差ΔＷに基づいて季節毎に必要とするオフピーク時電力需要機器数を機種別に算出する。そして、算出したオフピーク時電力需要機器数を管理会社の営業目標として設定する。 In the process of FIG. 2, the processes of steps S6 to S8 correspond to off-peak time management means.
Further, the system management device SD calculates the total power consumption at each predetermined time for each power demand group stored in the database to form the time chart shown in FIG. 3, and the leveling target total power is calculated from this time chart. Calculate usage, determine whether there is total power usage at a given time below the calculated leveling target total power usage, and there is total power usage below the leveling target total power usage When calculating the power amount deviation ΔW obtained by subtracting the total power usage from the leveling target total power usage, the number of off-peak power demand devices required for each season is calculated based on this power amount deviation ΔW. Calculate separately. Then, the calculated number of off-peak power demand devices is set as a management target of the management company.

一方、平準化目標総電力使用量を上回る総電力使用量が存在する場合には、ピークカット可能な機器数を電力需要グループＧ１〜Ｇ３毎に算出すると共に、各電力需要グループＧ１〜Ｇ３間で融通可能な電力量を算出し、融通可能な電力量がある場合には、これを電力量が不足する電力需要グループに供給する。
次に、上記実施形態の動作を説明する。 On the other hand, when there is a total power usage exceeding the leveling target total power usage, the number of devices capable of peak cut is calculated for each power demand group G1 to G3, and between each power demand group G1 to G3. The amount of power that can be accommodated is calculated, and if there is an amount of power that can be accommodated, this is supplied to a power demand group that lacks the amount of power.
Next, the operation of the above embodiment will be described.

各電力需要グループＧ１、Ｇ２及びＧ３では、電力会社に接続された高電圧受電設備２、１２及び２２を有しており、これら高電圧受電設備２、１２及び２２で高電圧電力を調達し、電力需要グループＧ１及びＧ２では電力供給制御装置３及び１３によって低電圧に変圧してから各需要家Ｄ１１〜Ｄ１ｎ及びＤ２１〜Ｄ２ｍに供給する。一方、電力需要グループＧ３では各需要家Ｄ３１〜Ｄ３５に設けられた高電圧受電設備２２で電力会社からの電力を調達して、需要家Ｄ３１〜Ｄ３５内で所定の低電圧に変圧して使用する。   Each power demand group G1, G2 and G3 has high voltage power receiving facilities 2, 12 and 22 connected to an electric power company. These high voltage power receiving facilities 2, 12 and 22 procure high voltage power, In the power demand groups G1 and G2, the power supply control devices 3 and 13 transform the power supply voltage to a low voltage and then supply it to the consumers D11 to D1n and D21 to D2m. On the other hand, in the power demand group G3, the high-voltage power receiving equipment 22 provided in each consumer D31 to D35 procures power from the power company, transforms it to a predetermined low voltage in the consumers D31 to D35, and uses it. .

そして、各電力需要グループＧ１〜Ｇ３では、各需要家Ｄ１１〜Ｄ１ｎ、Ｄ２１〜Ｄ２ｍ及びＤ３１〜Ｄ３５で使用した電力量が夫々電力積算計ＷＭ１１〜ＷＭ１ｎ、ＷＭ２１〜ＷＭ２ｍ及びＷＭ３１〜ＷＭ３３で計測されると共に、電力需要グループＧ１及びＧ２の高電圧受電設備２及び１２で受電した高電圧電力が電力積算計ＷＭ１０及びＷＭ２０で計測され、各電力積算計で計測された使用電力量が電力需要グループＧ１〜Ｇ３毎に分散管理装置ＭＤ１〜ＭＤ３に所定時刻毎に送信されて、これら分散管理装置ＭＤ１〜ＭＤ３で需要家コードと対応させて使用電力量が収集されて管理される。   And in each electric power demand group G1-G3, the electric energy used by each consumer D11-D1n, D21-D2m, and D31-D35 is measured by electric power integrators WM11-WM1n, WM21-WM2m, and WM31-WM33, respectively. At the same time, the high voltage power received by the high voltage power receiving facilities 2 and 12 of the power demand groups G1 and G2 is measured by the power integrators WM10 and WM20, and the power consumption measured by each power integrator is the power demand groups G1 to G1. Each G3 is transmitted to the distributed management devices MD1 to MD3 at predetermined time intervals, and the distributed power management devices MD1 to MD3 collect and manage the amount of power used in association with the customer code.

そして、各分散管理装置ＭＤ１〜ＭＤ３で収集された需要家コードと対応させた使用電力量が所定時刻毎にネットワークＮＷを介してシステム管理装置ＳＤに送信され、このシステム管理装置ＳＤで、電力需要グループＧ１〜Ｇ３毎に、且つ需要家Ｄ１１〜Ｄ１ｎ、Ｄ２１〜Ｄ２ｍ及びＤ３１〜Ｄ３５毎に所定時刻毎の使用電力量がデータベースに格納される。   Then, the amount of power used corresponding to the customer code collected by each of the distributed management devices MD1 to MD3 is transmitted to the system management device SD via the network NW every predetermined time, and the system management device SD uses the power demand. The electric power consumption for every predetermined time is stored in a database for every group G1-G3 and every consumer D11-D1n, D21-D2m, and D31-D35.

このため、システム管理装置ＳＤは、電力需要グループＧ１〜Ｇ３毎に所定時刻単位で総使用電力量を算出し、この総使用電力量から予め設定した需要ピークに近づいたか否かを判定し、需要ピークに近づいたときには、電力需要グループＧ１〜Ｇ３毎に、負荷低減指令を送信して、使用電力量を抑制するように制御し、総使用電力量がピーク時閾値を越えたときには予め設定された電力の制限を行っても影響が少ない電力機器について電力の制限又は供給停止を行う電力低減指令を送信する。このとき、電力需要グループ内に大電力を消費する冷凍・冷蔵倉庫を有する場合には、この冷凍・冷蔵倉庫を需要ピークが近づいたときに、通常の冷却温度より低い温度に過冷却し、需要ピークがきたときに必要最低限の電力のみを供給して、過冷却時の温度低下分だけ冷却能力を低下させることにより、ピークカット処理を行う。   Therefore, the system management apparatus SD calculates the total power consumption for each power demand group G1 to G3 in a predetermined time unit, determines whether or not the demand peak set in advance is approached from the total power consumption, and the demand When approaching the peak, a load reduction command is transmitted for each of the power demand groups G1 to G3, and control is performed so as to suppress the amount of power used. A power reduction command for limiting or stopping supply of power is transmitted for a power device that has little influence even when power is limited. At this time, if the electricity demand group has a refrigerated / refrigerated warehouse that consumes a large amount of electricity, when the demand peak approaches, the refrigerated / refrigerated warehouse is supercooled to a temperature lower than the normal cooling temperature, The peak cut process is performed by supplying only the minimum necessary power when the peak comes and reducing the cooling capacity by the temperature drop at the time of supercooling.

また、冷凍・冷蔵倉庫のようにピークカットを行うことができる設備を有しないマンション等で構成される電力需要グループＧ２では、負荷低減指令を受信したときに、共用部分で使用する電力を必要最低限とし、電力低減指令を受信したときに家庭用クーラー等の設定温度を通常時より高い温度に設定して、冷却能力を低下させることにより、電力低減処理を行う。   In addition, in the power demand group G2, which is composed of condominiums that do not have facilities that can perform peak cuts, such as refrigerated / refrigerated warehouses, when the load reduction command is received, the power required for the common part is the minimum When the power reduction command is received, the set temperature of the home cooler or the like is set to a higher temperature than normal, and the cooling capacity is reduced to perform the power reduction process.

一方、冬期や夜間のように、オフピーク状態にあるときには、例えば電力需要グループＧ２ではオフピーク時電力需要機器である床暖房装置を積極的に利用してオフピーク時の電力需要を増加させたり、電力需要グループＧ３では冬期にハウス栽培装置Ｄ３４や養殖装置Ｄ３５を積極的に稼働させて、オフピーク時の電力需要を増加させたりする平準化情報を送信して、電力の有効利用を行うことにより、需要ピーク時及びオフピーク時の総使用電力量を平準化する。   On the other hand, when it is in an off-peak state, such as in winter or at night, the power demand group G2, for example, actively uses a floor heating device that is an off-peak power demand device to increase the off-peak power demand, In group G3, the house peaking device D34 and the aquaculture device D35 are actively operated in winter, and leveling information that increases the power demand during off-peak hours is transmitted to effectively use power. Equalize the total power consumption during peak hours and off-peak hours.

一方、システム管理装置ＳＤでは、所定時刻毎に各電力需要グループＧ１〜Ｇ３から送信される需要家コードを対応付けた使用電力量を受信してデータベースに格納することにより、このデータベースに格納された各需要家の使用電力量から時刻毎の総使用電力量を算出して図３に示すタイムチャートを形成することにより、このタイムチャートの波形から平準化目標総電力使用量Ｗ*を求め、求めた平準化目標総電力使用量Ｗ*と実際の総使用電力量とを比較して、負荷制限処理の程度を決定すると共に、オフピーク時に必要とする電力需要機器数を算出し、これを管理会社の営業目標とすることにより、オフピーク時電力需要機器の販売を促進することにより、需要ピーク時とオフピーク時との総使用電力差を低下させてより精度の高い平準化処理を行うことができると共に、オフピーク時電力需要機器をレンタル又はリース契約とすることで、レンタル料やリース料が収入増加につながり、管理会社の運営自体も健全なものとすることができる。 On the other hand, in the system management device SD, the power consumption amount associated with the customer code transmitted from each of the power demand groups G1 to G3 at every predetermined time is received and stored in the database. By calculating the total power consumption for each time from the power consumption of each customer and forming the time chart shown in FIG. 3, the leveling target total power consumption W * is obtained and obtained from the waveform of this time chart. The leveling target total power consumption W * and actual total power consumption are compared to determine the degree of load limit processing, and the number of power demanding devices required during off-peak hours is calculated, and this is managed by the management company By promoting sales of power demand equipment at off-peak hours, the total power consumption difference between peak demand and off-peak hours can be reduced and more accurate leveling can be achieved. In addition to being able to perform normalization processing, rental or lease contracts for power demand equipment at off-peak hours will lead to an increase in revenues, and the management company itself can be sound. .

さらに、電力需要グループＧ１〜Ｇ３が電力需要状況が異なるグループに区分けされているので、各電力需要グループＧ１〜Ｇ３の単位時刻当たりの総使用電力量が異なることを利用して、余剰電力を生じたグループから需要ピークに近づいたグループに対して電力を融通することより、グループ全体の総使用電力の平準化を行うことができ、より効率の良い電力の有効利用を行うことができる。   Furthermore, since the power demand groups G1 to G3 are divided into groups having different power demand situations, surplus power is generated by utilizing the total power consumption per unit time of each power demand group G1 to G3. By making power available to a group that has approached the demand peak from the other group, it is possible to level the total power used by the entire group, and to make more efficient use of power more efficient.

なお、上記実施形態においては、電力需要グループとして３つの電力需要グループＧ１〜Ｇ３を適用した場合について説明したが、これに限定されるものではなく、任意数の電力需要グループを形成することができると共に、各電力需要グループ内の需要家数及び高電圧受電設備で購入する高電圧電力量についても任意に設定することができる。
また、上記実施形態においてはネットワークＮＷに１つのシステム管理装置ＳＤを接続して、このシステム管理装置ＳＤで電力管理を行うようにした場合について説明したが、これに限定されるものではなく、電力需要グループ数が増加した場合に、所定数の電力需要グループ毎に分散管理するシステム分散管理装置を配置し、これらシステム分散管理装置をシステム管理装置で管理するようにしてもよい。 In addition, in the said embodiment, although the case where the three power demand groups G1-G3 were applied as a power demand group was demonstrated, it is not limited to this, An arbitrary number of power demand groups can be formed. In addition, the number of consumers in each power demand group and the amount of high voltage power purchased at the high voltage power receiving facility can be arbitrarily set.
In the above embodiment, the case where one system management apparatus SD is connected to the network NW and the power management is performed by the system management apparatus SD has been described. However, the present invention is not limited to this. When the number of demand groups increases, a system distribution management device that performs distributed management for each predetermined number of power demand groups may be arranged, and these system distribution management devices may be managed by the system management device.

さらにまた、上記実施形態においては、電力需要グループで余剰電力が発生したときには、他の電力を必要とする電力需要グループに融通する場合について説明したが、これに限定されるものではなく、余剰電力を電力会社に売却するようにしてもよい。 Furthermore, in the said embodiment, although the case where electric power management was performed in an electric power demand group was demonstrated, it is not limited to this, Other energy resources, such as gas, can also be managed similarly to the above.
Furthermore, in the above-described embodiment, when surplus power is generated in the power demand group, the case where the power demand group that requires other power is accommodated has been described. However, the present invention is not limited to this, and surplus power is not limited thereto. May be sold to a power company.
